Read-only file system when running firmware script

Support

I have all the flags and proper output showing it’s unlocked. I get the Read-only filesystem error when running the script.

Warning: Failed to open the file firmware-util.sh: Read-only file system

I found someone with the same error that said they fixed it, but never told how…

Figured it out…
For anyone who runs into this, the instructions on chrultrabook leave out an important note that is on MrChromebox site. You must login as chronos when running the script, do not use root as done in previous unlocking steps.
